Objectives: To evaluate the efficacy of an augmented reality infrared navigation system (SIRIO) performance on computed tomographic (CT)-guided percutaneous lung ground-glass opacity biopsy. Complications rate and histological sample quality were evaluated, in relation to lesion size and location. Methods: A total of 40 patients over 18 years with lung ground-glass opacity suspected of malignancy were included. Patients with an affected coagulative profile or performance status were excluded. Maximum lesion diameter (LD), distance between lesion and pleural surface (DPS), distance traveled by the needle (DTP), procedure timing (PT), and validity of histological sample were evaluated. Complications rate in relation to the maximum diameter of the lesion and the distance traveled by the needle were analyzed. Results: Histopathological diagnosis was obtained in 92.5%, and the incidence of adenocarcinoma was reported as 75%. Mean LD was 16.0 mm, mean DPS was 13.5 mm, mean DTP was 71.0 mm, and mean PT was 15 ± 5 min. The thoracic radiation dose was 40.2 ± 49.1 mGy × cm. We reported only one case of major complication: a massive pneumothorax that required placement of a drainage. No statistically significant correlations were found either between the maximum LD and the complications rate or between the distance traveled by the needle and the same complications (P > 0.05). Conclusion: The SIRIO navigation system has demonstrated high safety, technical reliability, and effectiveness for percutaneous CT-guided pulmonary ground-glass opacity biopsies with a low incidence of complications and a reduction of the radiation dose administered to patients.
